  • Patent number: 5846235
    Abstract: A cryoprobe instrument for endoscopic use has been provided that permits the delivery of liquid or gaseous cryogens in the form of a spray. In an embodiment, the cryoprobe instrument includes an elongated, flexible tube having a fluid passage defined therethrough; a proximal connector portion provided at the proximal end of the tube for coupling the tube to a pressurized source of cryogenic refrigerant; and a nozzle tip mounted to the distal end of the tube. The nozzle tip has an outlet orifice constructed and arranged such that through the Joule-Thompson effect, cryogenic refrigerant exiting through the outlet orifice rapidly and substantially expands and cools.

  • Patent number: 5776160
    Abstract: A stent, for example for maintaining the patency of a duct such as a biliary duct, is provided that includes a plurality of radially extending wings. The wings project from a core which has a guide wire or wire stylet lumen. Each of the wings preferably includes a plurality of minute, longitudinally extending grooves for bile flow even in the event of tumor ingrowth. Advantageously the core itself is preformed into a helical configuration.
